Other than very specific issues related to Freak4, toddlers and ZBrush, which have garnered a lot of attention here, what are some of the biggest changes / improvements in SR3? I have read the ReadMe file, so don't need SM's list, but I am interested in real-world experience. Mostly in the area of stability.

The original PP2012 and SRs 1 and 2 were about as stable as a house of cards on a windy day on my Mac, so that I did most work on PP2010 and went to 2012 to render. Any Mac-heads doing all their work within 2012 with SR3?
